Refrigerators for various purposes (commercial, industrial, transport, household, etc.) are widely used in the national economy for storing of perishable goods. Refrigerators also differ in size, design, and operating principle. Food industry enterprises, transhipment bases, and large retail facilities (shops, supermarkets, food markets) are equipped with large-capacity refrigerators. The required temperature regime of the refrigerator is provided by a refrigeration machine. The operation of a refrigeration machine is based on the transfer of heat from the cooled space to the external environment. The load on refrigeration equipment is determined by heat inflows - thermal energy entering the refrigerated room from various sources. In accordance with the known methodology, an algorithm was compiled for calculating heat inflows into the refrigeration room. During the calculation process, heat inflows through the enclosing structures of the room (walls, roof, interfloor ceilings) from the air outside them, or from the ground, if the of the refrigeration chamber floor lies on a ground base, are determined. For external fences (walls, roof), heat inflows from solar radiation are also calculated. In addition, the calculation includes determining heat in-flows from refrigerated cargo and containers; from lighting fixtures; from people entering the premises; from air flow through opened doors; from electric motors operation. The total heat inflow is defined as the sum of partial heat inflows from all sources.
